Information about tests
Printing inks and coatings/ lacquers- Fastness;Suitability tests, resistance, hot alkali resistance
The tests may be carried out on printings, coatings on flexible substrates such as films or paper. We can test the suitability and resistance to various environmental influences, food fastness, chemicals, fastness, bleeding, deep freezing, sterilization, pasteurization, scratching, wrinkling, etc. If your special requirement is not mentioned here, please contact us.

Standardprüfungen
Alkali- resitance against hot soda lye (e.g. for label materials)A specified area of the printed (label) material is stirred in 2.5 % (m/m) caustic soda solution at 85 °C for 20 min at 250 rpm. The evaluation includes inspection of the surface of the (label) material [separation of layers (ink and paper), colour changes] and the colour of the solution. For comparative tests, the ink layer thickness of the test prints must be comparable, e.g. with printed labels.
Norm: ISO 12632
Bleeding fastness
This test method is used to test the resistance/color fastness of a print or lacquer to solid materials/media that can cause bleeding (color transfer). The solid media can be, for example, foodstuffs such as cheese or meat, technical products such as waxes, plastics containing plasticizers or natural materials. The printing/lacquering is contacted with the solid medium and, after a specified time under specified contact conditions, a test of the medium and the test surface for color changes is carried
Norm: ISO 2836
wrinkle resistance
Testing of the sample after storage in medium, e.g. water or other, under specified temperature for a defined period of time.
Norm: PV 03/ PV 03.1 SunChemical- Hartmann Druckfarben
resistance against media 1- immersion method (for solvents and other volatile media)
This test method is used to check the resistance of a print or lacquer to the impact of volatile media such as solvents, solvent-containing cleaning agents, gasoline, etc. The printed or lacquered material is immersed in the liquid medium for a specified period of time under specified conditions (safety regulations must be followed in the case of flammable and easily combustible media) for changes of the print surface or color changes of the medium.
Norm: ISO 2836
Media resistance 2- (for non-volatile liquids such as acids, alkalis, liquid soaps, detergents, etc.)
This test method is used to test the resistance of a print or lacquer to non-volatile, liquid media. The printed or lacquered surface is brought into contact with a media-soaked filter paper and this combination is stored between weighted glass panels.
Norm: ISO 2836
Bleeding fastness-Copy
This method is used to test the resistance of a print or coating/ laqcuer against steam sterilization (or full water sterilization on request) at Tmax.= 121 °C for 30 min.
Norm: DIN 16524-5
Sterilization resistance 130°C/ 30 min
This method is used to test the resistance of a print or coating/ laqcuer against steam sterilization (or full water sterilization on request) at Tmax.= 130 °C for 30 min.
Norm: DIN 16524-5
Deep freeze resistance
The sample is wetted with water, frozen at -20 °C for min 2 h and then tested for wrinkle resistance.
Norm: Sun Chemical Hartmann PV 16
